14.Claims. Cl. 137-499 The invention relates in general to fluid dispensing valves and more particularly tomultiple position disp'ensing valves having multiple discharge conditions.

Fluid dispensing valves such as may be used on soda fountains have heretofore been designed-and used, such as in my copending application Serial No. 363,619,

'for Gang Dispensing Valve With By-'Pass,-filed June 23,

one valve .need be periodically cleaned for sanitation.

Separately, soda alone ;may be desired to be dispensed, and in many cases suchias in mixing ice cream sodas, both a hard or concentrated stream sOda discharge and a soft or flowing soda discharge condition is desired.

Accordingly, an object of the invention is to provide a plural discharge condition dispensing valve to mix fluid froma common line with fluids from other lines and to separately control flow of fluid from the common line.

Another object of the invention is to provide a fourin-one dispensing valve which selectively will mix soda with either-of two flavoring syrups or extracts and'additionally will provide a hard or soft soda discharge condition.

Still another object of the invention is to provide a dispensing valve which contains a diffuser wherein soda water may be dispensed by one'valve plug through the dilfuser or may be dispensed by passage through first'and second valve plugs in series and'by-passing the diffuser.

Still another object of the invention is to provide a dispensing valve with first and second valve plugs which may selectively be connected in'series for a first discharge condition, and for a second discharge condition may be connected in-series plus .a re-entrant passageway through the first valve plug with each valve plug controlling the fluid flow.

Another object of the invention is to provide a dispensing valve with first and second handles eachhaving a neutral position and each having first and second alternative positions for selective control of fluid discharge.

Still another object of the invention is to provide a dispensing valve with a diffuser which may be used with a first valve plug in either of two positions and which also may be used in-one selective condition only of a second valve plug in the same dispensing valve.

Other objects and a fuller understanding of this invention may be had by referring to the following description and claims, taken in conjunction with the accompanying drawings, in which:

The :drawing shows the dispensing :valve 15 of the invention whichincludes generally-a housing 16, a supporting shell 1-7,-a.b0dy 18, first and second valve chambers 19 and 20, and first andsecond valve plugs 21 and 22. The supporting shell 17 may be cylindrical in shape andis designed to be mounted on'a soda fountain or the like for su'pportof the entire valve15. The shell 17 is hollow and surrounds first, second, and third inlet .lines 25, 26, and 27. The dispensing valve 15 of the invention may be used with various fluids; and one signed to mix fluids from the first and second lines 25 and 26 toprovidea flavored beverage such-as a cola drink, andgselectively to mix fluids from the-second and third lines to provide another flavored-beverage such as a ginger ale drink. 7 V

This intermixing of fluids is accomplished primarily'by the first valve plug 21inthe first-chamber -1-9"by means 'ofa =first handle -29 which has a neutral or intermediate position shown in-Figure l and also;has first and second operative positionsshown in phantom inthe drawing as positions 29A-and 293, respectively.

The valve body 18 is preferably formedof first'and second body halves 31 and 32 having semi-cylindrical inner surfaces 33- and 34, respectively, defining the first valve chamber 19 in which'the cylindrical first valve-plug 21 is rotatable. The'body halves31 and 32 are mounted in a frame 35 'which is connected'to a bracket 36-on the shell :17 by means ofbolts 37. The proper tightening of the bolts 37 squeezesrthebody-halves 31=andt32together to "makea fluidatight seal between the body '18 and the valve plug 21.

As bestshownin Figure 5, the inlet lines 25,-2.6,and 27 are'connected to the body half 31 at conduits 38, 39, and 40, respectively. As shown in Figures 5-to 10, the

valveplug -2-1rhas aplurality of bore means which selectively may register with the conduits 38, 39,-and 40. IA first bore 41 may selectively mesh with the first conduit 38. Asecond bore means 42' may selectively mesh with the second conduit 39, and a third bore 43 may selectively mesh with the third conduit 40. The'second-bore means -42*includessix bores'44 to 49, inclusive, generally radially disposed in the valve plug 21. A 'by-pass passageway 50 may alsoselectively register-with the second conduit 39.

The Figures 1 and 5 to 10 are shown with the handle 29 in the neutral or intermediate position. The-Figures 7, 8, and 10 show that in such case the bore means 41, 42, and 43' are closed to communication fromthe Patented Mar. 21, 1961,

With the handle 29 in the position 29A, which may be considered a first operative position, the first, bore 41 meshes with or is in fluid communication with the first ,fluid conduit 38 to pass fluid to a conduit 52in the second body half 32 which conduit 52 has a lower opening 53,

Figure 4,. to empty into the housing 16 and 'thus pass to the discharge opening 54 of this housing 16. Concurrently, the bore means 42 is so positioned that the bore 44 is in communication with the conduit 39; hence,

the housing 16. In so doing thesoda water washes the inner walls of the housing 16 to thoroughly cleanse same of any syrup or extract discharging from the lines '25 I or 27 and also the soda water in passing through the diffuser has a chance to release the carbon dioxide gas therein so that it has a soft foaming type of discharge.

When the handle 29 is moved to the alternative operative position shown at 29B, the bore 43 is placed in communication with the conduit 40 to pass a second f flavoring syrup or extract to a conduit 59 in the second body half 32. Conduit 59 has a lower opening 60 which passes this fluid to the discharge opening 54 of the housing 16. Concurrently, the second fluid, such as soda water, passes through the second bore means 42 which or fluid from the second inlet line 26 passes through the by-pass passageway 50 of the first valve plug to the soda inlet 51, from there through the passageways 63 and 65 of the second valve plug 22 to return through a conduit 82 to re-enter the first valve plug 21 at the second bore means 42. In this case, the second bore means 42 includes the bores 47 and 49 so that the soda water passes through the body outlet 55 and through the diffuser 57 to the discharge opening 54. This provides a soft soda discharge condition of the valve 15. The Figure 11 shows the alternative or second operative position of the handle 68 wherein soda water again passes through the by-pass passageway 50; the soda inlet 51 to the valve plug 22, whereat it passes through the passageways 64 and 63 to a conduit 83 to which a tube 84 is connected. This tube 84 delivers the soda water directly to the discharge opening 54 without re-entrant passageway through the first valve plug 21 and without passage through the diffuser 57. Since the diffuser is by-passed in this condition, the soda water is delivered in a fine, hard, and concentrated stream suitable for mixing ice cream sodas and the like.

This dispensing valve 15 thus has four different conditions effected by the two two-way valve plugs 21 and 22. With the handle 29 in either of the two operative positions, a soft soda discharge condition is effected through the diffuser 57 which in such case aids mixing of the soda in this case includes the bores 45 and 48, and passes through the body outlet 55 and the diffuser 57 to the discharge opening 54.

With the handle 29 in the neutral or intermediate po- 1 sition, only the by-pass passageway 50 is in communication with the line 26, and this permits the second valve chamber 20 to become operative; This second valve chamber 20 is in the forward end of the second body half 32 and contains the second valve plug 22. The second valve plug 22 has passageways 63, 64, and 65.

' These passageways make the valve plug 22 a two-way valve. second valve plug 22, and this may be done by the set screw 69. A sleeve 70 has a tapered shoulder 71 which The'second handle 68 may be attached to the fits on the inside of the frame 35 at an aperture 72. A valve stem 73 is journalled inside the sleeve 70 and in turn has a cylindrical shoulder 74 with a diametrical slot 75 which is at a forty-five degree angle relative to the vertical when the handle 68 is vertically disposed in a neutral position, as shown in Figures 2 and 4. The

valve plug 22 has a bar 76 to interfit with the slot 75 so that turning of the handle 68 provides turning of the valve plug 22. The interior of the sleeve 73 is i threaded at 77 to receive a cone point set screw 78 which engages a cone point recess 79 in the valve plug 22.

This forces the valve plug 22 axially into the second valve chamber 20 so that the flat front face 80 of the valve plug 22 is in fluid sealing engagement with the valve chamber 20. A locking set screw 81 may engage the rear of the cone point set screw 78 to lock the screw 78 in place.

The Figure 4 shows the front of a valve body half 32 and it also shows the valve plug 22 removed therefrom and turned one hundred eighty degrees so that Figure 4 shows the front face 80 of this valve plug 22. This valve plug 22 is in the neutral position as shown in Figures 1, 2, 4 and 5, whereat the handle 68 is vertical, and the bar 76 and slot 75 are at a 45 angle to the vertical. In Figure 4, comparing the position of the valve plug 22 and the ports 63-65 therein, it will be noted they are not in registration with the ports 51, 82, 83 in body portion32; hence this second valve plug is in a closed condition. The

water with whatever syrups or extracts are also passed to the discharge opening 54 from the inlet lines 25 and 27. With the handle 29 in the neutral position, then the handle 68 becomes operative to provide either a soft soda discharge condition by passing the soda through the diffuser 57 as shown in Figure 12 or to have a hard soda discharge condition as shown in Figure 11 wherein the diifuser is by-passed. In the position of the'valves as shown in Figure 12, it is noted that the fluid communication is first through the first valve plug 21, next through the second valve plug 22, and then re-entry through the first valve plug 21 so that the fluid may pass through the ditfuser 57 by passing through the body outlet 55. This permits the dispensing valve 15 to be very compact because only one diffuser is needed even though a soft soda discharge condition is controlled by the second valve plug 22. Since the diffuser 57 and its associated cylindrical chamber 56 is rather bulky compared to the rest of the valve, there is a saving in space, weight, and complexity of the valve 15 and it also promotes ease of cleaning since only one diifuser need be cleaned for a total of four different types of fluid dispensed.

The diffuser 57 has a triple purpose; namely, it permits the soda water stream to be broken up so that it is a soft flowing condition, it permits a great bulk of the carbon dioxide gas to be released from the soda water so that the liquid as dispensed is not so foaming and bubbling as to fill the glass principally with bubbles, and third it permits-a diffusion and dispersing of the soda water so as to wash down the inner walls of the housing 16 to thoroughly cleanse these walls of all syrup or extract from the lines 25 and 27 so that successively different flavored beverages may be dispensed with no intermingling of flavor.
